What does Hebrews 1:2 mean?
Verses 1 and 2 of Hebrews emphasize the fact that Christ is the latest part of God's continuous, consistent message. Where God had spoken through the prophets of the Old Testament, He now speaks through the person of Jesus Christ. These are not contradictory messages. Jesus is the Messiah of whom those prophets spoke. Since this is a message from God, it stands to reason that those who love God ought to listen. Knowing that Jesus is a message from God, and is God, and is the ultimate truth sets the table for this letter's many warnings against rejecting the gospel.The end of verse 2 also introduces an idea which is fundamental to the Christian faith: Jesus Christ is God. The first four verses of this book establish that Jesus is not some created being or a higher form of angel. According to verse 3, Jesus is the "exact imprint" of the nature of God. This is the consistent teaching of the Bible, that Christ is both fully God and fully man.
The words of this verse echo the Gospel of John, which notes that "all things were made through [Christ], and without [Christ] was not any thing made that was made" (John 1:3). This establishes that Jesus is, in fact, part of the un-created and eternal God. All things which "were made" were made by God; the only thing not "made" is the eternal Creator.
